Individuals occur (rarely) on floor of Yosemite Valley and are reported at even lower stations. Lives in coniferous trees, chiefly lodgepole pines. Solitary. The Yellow-haired Porcupine is perhaps one of the best known of our native mammals, by reputation at least, though not all the stories which are current concerning it are accurate. Being of sluggish disposition and active by day as well as night it gives visitors in the high Sierras many opportunities to observe it at close range. And should these fail, the work of the animal is evident in many places. In general, the porcupine is to be found in the high Sierras above the level of Yosemite Valley; its range is practically the same as that of the lodgepole pine. Occasionally, however, individuals are observed at much lower levels. We were told, for example, of one trapped on the floor of Yosemite Valley in September, between 1916 and 1918. We have been told of individuals seen on Bullion Mountain. And at Snelling one resident told of a porcupine which he had shot in the river bottom a mile from town, and of two or three others, possibly castaways brought down the river in drift, which had been observed in the same whole cjuill cn\k) tip of quill f'S) base of quill fy5) Fig. 26. Quill from Yellow-haired Porcupine showing details of tip and base. At the tip are numerous small barbs which when the quill penetrates skin or flesh keep it from being pulled out; at the base is the slender and weak connection which makes for ready separation of the quill from the skin of the Porcupine. The porcupine's chief claim to attention lies in its covering of sharp- pointed hollow quills which are especially d
